The performances in the film are slightly unrealistic at times. Especially Collin Farrell's performance. He is trying way too hard to be cool. But for some reason it all just works. Especially I like the part where Elizabeth Rodriguez's character talks to a guy with a thumb on a bomb's activator. It's just the right amount of over the top coolness for the moment. It was so good, I think it's got to be my favorite moment in the entire movie.
I did not expect Spy Kids Armageddon to be any good. It is written and directed by Robert Rodriguez. A guy who doesn't care about quality that much. His view on film-making was shaped by his first filming experience in 1992 when he made El Mariachi. A movie so cheap that it was weird to a lot of people that it was an action film. Rodriguez has this idea that he can cheat his way into making anything at all. Using as he says "creativity instead of money". So most of his movies tend to look like the Star Wars prequels. A lot of pretty noticeable green screen. Tons of CGI where most other people would use practical props. And strange camera work which is probably more dictated by the limitations of his methods, and not by actual directorial decisions.
